I want to install a triple wall flue in my house which has a metal roof. I know how to install one in shingle roofing. But the metal won't work the same way. Is the roof jack just caulked and flat screwed?

Either rent, borrow or buy a set of roof ladder hooks with wheels. Goes over peak of roof.

Can we get a pic? Is it a standing seam roof?

I can get a picture. It's the screwed down type. I have no problem getting on the roof or cutting the hole. I just don't know the standard practice of securing the jack.

There is a roof jack with a rubber gasket bonded with lead of tin that you screw down over everything. The screw interval is very close. Silicone caulking as well. Some are regular, some are heat resistant.

This. What he is asking for would be called a flashing in some places. A jack to most people would be something you install to walk on a roof of about 7/12 pitch of steeper so you dont fall off.

Generally the ones les mentioned are only rubber boots with a malleable alloy that allows you to bend them over the ribs of the metal. I have only ever seen them for vent pipe boots, not woodbuning stoves.


When doing a new install for (I am assuming a wood stove) I would use two metal sheets and a standard chimney flashing. Install the lower sheet first, and cut the hole for the flue. Install the flashing, then put the second sheet over it on the upper side just like a shingle so it overlaps the lower sheet with the flashing in the middle . Tar all around it.

Easier to show than explain, and tougher to do as an addition rather than new. Will likely involve one more sheet of metal

There is a flashing for insulated chimney pipe. Same program, quite large.

Does it have an aluminum flashing attached to the rubber base? The aluminum ones I have used have an inch or so of air space around the insulated pipe. The overflashing gets caulked onto the pipe above it to shed water.

Or are they all rubber?

They are called EPDM stove pipe flashings for metal roofing. They screw down about 3/8. Do not use black tar as a exposed sealant it always cracks and leaks. I would recommend a urethane caulking it out lasts silicone and adheres to most surfaces. A brand I always use is SikaPro you can find it at Home Depot in the masonry section. EPDM flashings are commonly used on plumbing vents like Trapper Les was saying. They are a quality product. Depending how low on the roof you are installing your stove pipe there are a couple things I would suggest. If low on the roof install a cricket or something to keep the snow and ice from pushing the stove pipe over onto the roof. For proper draft your stove pipe has to be 2 feet higher than anything within 10 feet of it.

That's what I was after thank you. Are the black plastic pieces for plumbing pipes not called rook jacks? But yeah, flashing is the term I was looking for.

There will be a storm collar that you tighten down to the chimney pipe but over the flashing itself to seal things.

Joemac usually the stove pipe flashings are a orange/red color for heat resistance material. Be sure to use braces to secure the pipe above and below the roof. The EPDM flashings have no strength to hold the pipe from falling over.

The flashing you will need is dependent on your roof pitch .... I needed a steep angle flashing for my 9/12 pitch .... I also used heat resistant silicone around the storm collar ....
